Research topics

Our activities lie in the field of experimental solid-state physics, with the following core areas:

Magnetic thin films

We examine growth and magnetic properties of films that are just a few atomic layers thick. A range of different methods is used for analysis, including electron diffraction and rotation of light polarization by polar Kerr effect.

Near-field optical microscopy

In this method, the electromagnetic field emitted by the tapered end of a glass fiber is used as a probe. We have been developing such microscopes for years,using them to examine magnetic and optical properties on a nanometer scale. The method is also ideally suited to examining biological systems.
